Answer / daxity

Obviously there is problem because the currents are not
balanced.the cause might be an imbalance in the winding
resistance which might come from unequal number of turns or
deffective insulation on that particular phase,or loose
connections on that phase from point of supply to the last
termination.........if the windings are perfectly
balanced:-misalignement and bearing failure can affect all
the phases.
